comparision of floating value

[prasannabalaji]

hi,

is it possible to compare floating point values
for example

a=3.14;
if(a>4)

Yes, you can mix data types in C, such as adding (or comparing) together an integer and a floating-point value. C generally converts the smaller of the two types into the other.
The expression if (a>4) mixes the variable "a" of type float and the constant "4" of type integer.

Warning: it is unsure to perform some comparisions because of roundoff errors.
For instance, the following code can give unexpected results:

b=a/c;
...
if (a==b*c) ...

if its C, you can mix data types, and remember that the smaller data type is automatically converted to the bigger type of the two while mixing...
